[Specific problem related to oro maxillo facial sphere and hwaring in 340 Lebanese musicians practicing wind instruments]

The aim of this study is to detect the problems related to wind instruments in order to determine the contributing factors. This study is a prospective study of a sample of Lebanese wind-instruments musicians. Questionnaire of 17 items about personal data, musical activities in general and specific problems related to wind instruments. 340 response out of 400 [85%]. Gender: male 100%. Age: 28.5 +/- 6.5 years [13-50]. Practice of any physical activity: 57.5%. Smokers: 40.5%. Data about musical practice-Years of practice: 6.5 +/- 5.5. Daily practice: 2.5 +/- 1.5 hours with 35 +/- 2 rest periods of 16.5 +/- 15 minutes. Weekly practice: 5 +/- 2 days. Data about medical problems-Hear loss 34%; respiratory difficulties: 19.5%; wound of lips muscles: 5%; gums and tongue lesions: 7.8%; myospasms of the cheeks and lips: 34.5%; dental problems: 30.7%temporo-mandibular disorders [TMD]: 22.5%. There is a high association between risk factors and pathology. Risks related to the instrument's use: hear loss [p=0.001], traumas to lips muscles [p=0.065], myospasms [p=0.064], TMD [p=0.000]. Other factors: physical activity is beneficial; smoking is harmful [breathing difficulties, spasms, headaches]. Factors influencing the different problems: age [31 +/- 7 years]; years of practice [9 +/- 6]; hours of practice per day [2 +/- 15]; days of practice per week [4.5 +/- 2.5]. Wind instruments are related to problems of mouth, facial muscles and hearing. This may lead musicians to stop their activities or to irreversible professional disabilities. A medical follow-up during the musicians training is needed to prevent these problems

Selective grinding for ternporomandibular disorder patients: indications and limits

The accumulation of data on the broad question "are occlusal interferences deleterious" has been gathered for over 68 years. If the role of occlusal factors in the etiology of Temporomandibular disorders has been overestimated in the past, this subject is still debated and the efficiency of occlusal corrections as a treatment modality for TMD patient is still controversial. In this article, we aim to respond to the question whether occlusal adjustment by selective grinding is still indicated for TMD patients and to define its indications and the limits of this procedure. In the absence of randomized clinical trials demonstrating that elimination of occlusal disturbances is an effective treatment for TMD, we recommend that this procedure should be well Joined by its indications, reversible and conducted with caution
